About Me

I’m an ML researcher at OpenEvidence, on a mission to revolutionize healthcare through AI. πŸ₯✨

I believe LLMs have the potential to transform how we augment human capabilities. My research focuses on building more reliable LLM systems that can genuinely support critical decision-making.

Previously, I was an Applied Scientist at Amazon AWS, where I pioneered LLMs for medical scribing.

I earned my Ph.D. in Computer Science from MIT in 2023, researching language model robustness and synthetic data, and my B.Eng. from Tsinghua University.
